(Original title: Love pipe sesame thingsWhich cities by the impact of the longest PM2.5 PM2.5 20 most polluted cities, Hebei occupies 15, are located in central and southern Hebei "Oriental Outlook Weekly" reporter Yang Zhuoqi / Shanghai reports Which living area of the country the best air quality? Your home where street PM2.5 exceeded a few days a year? The answer can be found in cities from Beijing National Laboratory PM2.5 distribution map. Dr. Long Ying of Beijing City Lab sponsor, the Chinese Academy of Geography Dr. Wang Jianghao, Dr. Wu Kang Capital University of Economics and the University of California, San Diego, Dr. Zhang Junjie, 945 ground-based monitoring of the country from April 2013 to April 2014 year publish PM2.5 monitoring data station, as well as daily remote sensing of atmospheric aerosols in the international community for the first time estimated daily PM2.5 concentration level of Township neighborhood offices, combined with the 2010 national census data, PM2. potential exposure of the population affected by Proposition 5 conducted the study. Beijing Urban laboratory will be refined to a national study about 40,000 township streets. People can be found among this year PM2.5 specific number of days exceeding air through the streets of their own villages and towns where the map. The study found that in accordance with the PM2.5 24 hourly average of 75 micrograms / cubic meter standard currently used in our country, the number of days per year in our country suffer from PM2.5 pollution is 113 days, about 223 million people live in an environment in more than six months exceeded time. Some streets contaminated year over eight months Beijing city lab will focus on research potential "human" and population exposure. "What is the population across the country exposed to PM2.5? At what time, which is the biggest threat to the region? These questions are we trying to answer." Long Ying of the "Oriental Outlook Weekly" said. According to his research.
255 days Palace, Handan 253 days, 253 days LINQing, Shijiazhuang 252 days. Beijing PM2.5 exceeded the number of days 161 days, ranked No. 125 (low), 204 days in Tianjin, ranked No. 42. PM2.5 20 most polluted cities, Hebei occupies 15, are located in central and southern Hebei. The shortest exposure time in Lhasa and Xigaze city, are two days. Followed by peace six days, seven days Yuxi, Southampton eight days, Xiamen eight days, nine days, Quanzhou, Zhangzhou and 10 days. Before 20 cities mainly in Tibet, Yunnan and Fujian.

In Beijing, Tianjin and Yangtze River Delta region, pollution center Shanghai and Beijing are lighter than the surrounding cities. According to the 2010 sixth national census data, we can see, almost all densely populated streets are the most polluted areas. Beijing PM2.5 exposure to the highest intensity PM2.5 impact on health and more attention. World Health Organization recently released data show that in 2012, about 700 million people worldwide die from air pollution-related diseases, including Southeast Asia, the Western Pacific region is the most serious. State Family Planning Commission had earlier said the impact of the long-term continuous monitoring haze on human health caused by the haze to assess risks to human health.
there are three PM2.5 pollution hotspots, a regional pollution is most concentrated quadrilateral Beijing, Chengdu, Guangzhou, Shanghai composed of four points across large areas of eastern, central part. The other two areas are in northeast China's Harbin - Shenyang line, and Urumqi as the center of the northern region of Xinjiang. PM2.5 exceeded the year in these areas most of the time more than three months. The study found that in April 2013 to April 2014, parts of the country's 827 million population live, PM2.5 exceeded the national standard (75 micrograms / cubic meter) three months. About 4100 streets.
nearly 11 percent of the township streets Office contaminated more than six months, mainly in Beijing, Tianjin, Hebei, south and central, central and eastern Henan, Shandong and Hubei in the Central West and Central. The high exposure of the total area of the region is 347,000 square kilometers, accounting for only 3.65 percent of the continent's land area, but accounts for the affected population of nearly 17 percent of China's total population, over 223 million people. In some streets in southern Hebei, northern Henan and western Shandong, the number of days a year contaminated more than eight months, even up to nine months. By contrast, in less than three months in January pollution of township streets office only 18,664, distributed in Tibet and northwest China, part of the southeast coastal areas (Fujian, Guangdong, Hainan), and southwest border areas (Yunnan, Guizhou Guangxi). Although the low-risk area covers three-quarters of the land area, but holds only 38 per cent of our total population. The longest exposure time is Xingtai city From a single city, China's cities by PM2.5 which affect the longest? According to the Beijing city laboratories number of days exceeding the rankings, all the country's cities above the county level, exposure is the longest city of Xingtai, a total of 279 days.
